Step 3. Set the input filter.
Set the low-pass filter with the L.P.F. key (8).
The low-pass filter of this module is a gently sloping attenuation filter that prioritizes the waveform.
Set a cutoff frequency about 10 times the effective frequency as a signal to remove the
unnecessary high frequency component and noise component.
OFF
3 kHz 300 Hz 30 Hz
3 Hz
Set the antialiasing filter setting with the A.A.F. key (9).
A steeply sloping attenuation low-pass filter. Enable this filter to automatically set the cutoff
frequency linked with the sampling speed so that aliasing does not occur in the measurement due
to the sampling. This is particularly effective for FFT analysis. The L.P.F. setting is disabled
because L.P.F. is used internally.
Step 4. Set the display range and display position.
See the description in "4.2.2.
Set the input channels - Display Range and Display Position (Display
".
Disp. range: The display width in the amplitude direction of the waveform display area on the
waveform monitor
Disp. pos.:
Specify the position of the waveform monitor to display the specified range of the
waveform display area.
Step 5 Set the display minimum and display maximum.
See the description in "4.2.2.
Set the input channels - Display Range and Display Position (Display
".
Disp. max:
Set the display upper limit value of the top of the display range.
Disp. min:
Set the display lower limit value of the bottom of the display range.
Step 5. Execute zero cancellation.
After turning on the power, changes in the surrounding temperature as time elapses change the
internal temperature of the RA3100 main unit, and cause temperature drift inside the input module,
which leads to errors in measurements due to variation in the DC offset voltage. Execute zero
cancellation to minimize these errors.
To perform zero cancellation, tap the Zero adjust key (14) after waiting for a warm-up period of
60 minutes.
NOTE
This function is for canceling internal offset and drift, and does not cancel the offset of the input signal.
